batterylife tips

hello, I just got a 3g and am tryxing to figure out a way to conserve battery life at night while I sleep. I turn off the wireless and the pushing and fetching features yet I still wake up with the 10% battery warning. I am hesitant to leave it plugged in for fearnthat it drain the battery faster in the long term. Also I use the alarm feature to wake up...but as far as I know that's the only thing running in the backgroung.
